About this watch
The Omega Constellation Co-Axial 31 is a stunning luxury watch that combines exquisite design with advanced technology. Its stainless steel and red gold case beautifully fuses style and sophistication, while the white mother-of-pearl dial catches the light in such a way that it seems to change color as you move. The Dauphine hands glide smoothly across the dial, providing both precision and style. At the heart of this watch is the remarkable Omega caliber 8520 movement, featuring the Co-Axial escapement, which reduces friction between moving parts and enhances the watch's precision. This certified chronometer has passed rigorous tests to ensure its accuracy and can be trusted to keep ticking even when you take it off for the weekend. With a water resistance of up to 100 meters, this watch is built for life! It's not just a luxury accessory; itβs a versatile companion that seamlessly transitions from a day at the office to a night out on the town. Whether you're a watch enthusiast or someone looking to make a statement, the Omega Constellation Co-Axial 31 fits the bill.
